On March 16, the Hubei Chibi Yangtze River Highway Bridge was successfully closed.
The bridge is the world's largest steel-concrete composite beam cable-stayed bridge.
The project starts at Shuifu Village, Wulin Town, Honghu City, and ends at Pu'an Village, Chibi Town, Chibi City, with a total length of 11.2 kilometers, of which the Yangtze River Bridge is 3.35 kilometers in length and the main bridge is 1,380 meters in length.
The whole line adopts two-way six-lane expressway standard construction, and the design speed is 100 kilometers per hour.
The Chibi Yangtze River Highway Bridge adopts a 720-meter main span double tower symmetrical combined beam cable-stayed bridge.
The main tower of the bridge adopts "H" shape design, the north tower is 217.33 meters high, and the south tower is 223 meters high.
The project's innovative design methods and process methods have overcome many world problems such as the concrete pouring of large-volume caps, the one-time vertical transmission of ultra-high main tower concrete, the long-span steel-concrete composite beam cable force of 720 meters, and the control of bridge alignment.
